Testing in other browser, or disabling the PPAPI version of Flash fixes the problem, so it seem likely there is something odd with the sound playback for the PPAPI version of Flash.
The problem is easier to spot if you try using a version in another browser a few times to get a feel for how the colour change and sound playing should behave.
